From: podaac.jpl.nasa.gov/glossary/
An archive is a collection of computer files that have been packaged together for backup, to transport to some other location, for saving away from the computer so that more hard disk storage can be made available, or for some other purpose. An archive can include a simple list of files or files organised under a directory or catalog structure (depending on how a particular program supports archiving).
